Jackson resident John Wilson turned in 110 signatures to run for mayor, but after a review by city officials, it was found only 82 were valid. Wilson needed 100 signatures of registered city voters to be placed on the Aug. 6 primary ballot.

"Some people signed that weren't city residents; some people signed more than once," Jackson City Clerk Andrew Wrozek said. "Now there's just the one contentious vote in ward 1 this August."

Voters will whittle down four candidates running for ward 1 City Council to two during the primary election Tuesday, Aug. 6.

The candidates include incumbent Michelle Woods and challengers Arlene Robinson, Gloria Ham and John Clemens.

All other races have two candidates or less, meaning all the candidates for Jackson mayor and City Council members in wards 3 and 5 will advance to the general election to be held Nov. 5.

Third ward incumbent Dan Greer is running unopposed.

In ward 5 incumbent City Council member Andrew Frounfelker faces challenger Susan Murdie.

Incumbent mayor Martin Griffin will take on challenger Jason Smith to sit atop Jackson City government.
